Thanks Ty-Fry-Typhoon, that's cleared up all the questions I had about what to expect during the training
Not so much step into the unknown anymore. 4-5 weeks is really good going and I'll be happy if I'm ready for the test anywhere near that time frame, although at my experience level and this time of year I expect it will take a bit longer.
I've heard that about the IR, not so unpredictable, and after the finishing the CPL its going to be a refreshing change, in fact I'm really looking forward to getting stuck into some proper flying! Thanks again
